Brinellhårdhedsprøvningen
Brinellhårdhedsprøvningen is a method used to measure the hardness of materials. Developed by Swedish metallurgist Johan August Brinell in 1900, it is one of the oldest and most widely used hardness testing techniques. The test involves pressing a hardened steel or carbide ball of a specified diameter into the surface of the material being tested under a specified load. The diameter of the indentation left by the ball, along with the applied load and the ball's diameter, are then used to calculate the Brinell hardness number.
The Brinell hardness number (HBW) is expressed as the load divided by the surface area of the
Brinell hardness testing is particularly suitable for materials with a coarse or heterogeneous microstructure, such as
